Title: compression test 4BD1
Post by: Johno on June 05, 2019, 11:54:32 AM
Gents has anybody done a compression test on a Perentie. do you do it via the glow plug or injector hole. Somebody suggested that you should have between 375 to 400 PSI ???? Any advice would be appreciated. JohnO

through the glow plug hole with the adapter from the compression tester. Not sure of the pressure some others might help or if in doubt go to the manual.

most good diesel testers come with a set of adaptors in the kit. Good luck
